Editing Online

Forms and editing widgets have already been configured in the tutorial project for both the buildings geometric layer and the related interventions_maintenance attribute table.

Editing settings are defined partly in the QGIS project (e.g. form layout), and partly through the G3W-SUITE Administration panel (e.g. user permissions). The editing module supports direct edits on both geometric and attribute-only layers, as well as layers in 1:N or N:M (limited) relationships.

Hint: In QGIS, the form layout and widgets for each layer’s attributes are configured under: Layer Properties → Attributes Form.

G3W-SUITE supports multi-user editing through a feature locking system.

When a user activates editing in the WebGIS interface, all features visible in the current map view become locked to that user. Other users will be restricted from editing these features until the original user exits editing mode.

Note: Multi-user editing should only be enabled on layers stored in a GeoDatabase — not on file-based layers (e.g. shapefiles).
